In fairness a government should be the only entity surveilling people in its own borders under most any circumstances.
I’m pretty opposed to most any kind of surveillance outside of warranted due process, and I don’t think that any domestic surveillance needs privacy for longer than it takes to do an investigation and prosecution.
It’s when governments are allowed to do things in secret and outside of the law that the whole concept of the law is undermined.










This CO2 is acting as a reusable fluid in a closed loop. The initial capture of the CO2 costs energy, but the battery keeps using the same CO2 over and over again. So the question of efficiency should be more about land usage and maintenance of the rest of the parts and the labor needed for each megawatt stored vs what other grid scale energy storage costs in materials and labor.
The rough reality is that batteries aren’t going to be up to the task of grid scale energy storage unless they have a couple huge breakthroughs. Something like this is a far less materially expensive way to store energy for later use.
Currently most grid scale energy storage is just pumping water up a hill and letting it back down through a generator. It is extremely limited in where it can be used and requires tremendous space to be effective.
